On the night of July 4, an underground transformer exploded near Bourbon and Conti Streets, cutting power to hundreds of French Quarter customers during one of the busiest weekends of the year. Festival crowds filled the area, hotels moved guests, and businesses that had been operating on packed streets suddenly found themselves sitting in the dark.
No one was injured, but the outage raised a practical question for every business owner in Greater New Orleans: if your building loses power, how much of your security system continues working?
At ABC Fire & Burglar Alarm, that question comes up frequently during hurricane season, severe weather events, and utility interruptions. Many businesses assume their alarm, cameras, and monitoring will continue operating as usual, but the answer depends on how the system was designed, how it communicates, and whether its backup equipment has been maintained.
Power Interruptions Create More Than an Inconvenience
The French Quarter outage was not an isolated event. Entergy New Orleans reported more than 300,000 customer interruptions during 2025, the highest total in several years, with equipment failures accounting for a substantial share.
For a business, even a brief outage can affect much more than lighting and point-of-sale equipment. Security panels may switch to battery power, video systems may stop recording, and electronic access control may behave differently depending on how it was configured. If internet or phone service is interrupted at the same time, the system may also lose its primary communication path.
These limitations are not always apparent during normal operations. A panel can appear to function correctly for years while relying on an aging battery that no longer holds a meaningful charge. Cameras may record consistently until the recorder loses power, and an older alarm may still communicate through infrastructure that becomes unreliable during a wider utility disruption.
That is why reviewing commercial security before the next outage matters. The goal is to understand how the system will behave while the building is dark, employees are gone, and the owner may not be able to reach the property.
A power outage should not reveal weaknesses in your security system. Call 504-889-9795 or schedule a commercial security consultation with ABC Fire & Burglar Alarm.
What Should Continue Working When the Power Fails?
A commercial security system needs several layers of support if it is expected to remain useful during an electrical interruption.
That review should include:
- Battery backup for critical alarm equipment
- A secondary communication path, such as cellular service
- Continued recording for essential video coverage where appropriate
- Current monitoring and emergency contact procedures
- Remote access that remains available whenever communication service allows
Battery backup is usually the first line of support, but its value depends on condition, capacity, and the amount of equipment drawing power from it. A battery installed years ago may still appear connected without providing the runtime the business expects. Regular testing helps identify that problem before an extended outage places the system under real demand.
Communication also deserves attention. Systems that rely only on older phone lines or on-site internet may be unable to transmit alarm signals if those services fail with the power. Cellular communication provides another route to the monitoring center, reducing the system’s dependence on a single utility or connection.
Video presents its own challenges because cameras, recorders, network equipment, and displays all require power. Backup planning should focus on the areas where continued visibility matters most rather than assuming every camera will remain online indefinitely. The right approach depends on the property, the risks, and how long the business needs critical coverage to continue.
A Dark Property Operates Differently
The loss of exterior lighting changes a property immediately. Entrances become harder to see, camera images may lose clarity, and employees or neighboring businesses are less likely to notice unusual activity.
During the July 4 outage, NOPD added patrols around affected areas while officers also managed crowds, traffic, and evacuations. That response helped support public safety, but businesses still needed their own systems and closing procedures to remain dependable during an unusual operating environment.
A monitored alarm system can continue transmitting signals while backup power and communication remain available. Cameras may provide visibility into critical areas, and remote access can allow owners to check system status without immediately returning to a dark building. Those capabilities become especially valuable when streets are congested, access is restricted, or the property remains unattended longer than expected.
The system does not need to eliminate every risk associated with a utility failure. It needs to preserve enough communication, detection, and visibility to give the business useful information and support an appropriate response.
Why Local Service Matters
Electrical interruptions in New Orleans are shaped by local conditions, including aging infrastructure, severe weather, flooding, festival traffic, and the practical difficulty of reaching certain areas when streets are congested or closed.
ABC Fire & Burglar Alarm has served businesses throughout Greater New Orleans for more than 20 years. That experience informs how systems are evaluated, where backup capabilities are most important, and which parts of the property need to remain protected when normal operations are disrupted.
Local service also matters after the system is installed. Batteries age, business layouts change, and communication equipment becomes outdated. Having a nearby team that can review those changes helps keep the system aligned with the way the property currently operates.
Review the System Before the Next Interruption
Another utility outage will eventually affect businesses somewhere in the New Orleans area. The timing may be uncertain, but the condition of your security system does not have to be.
A system review can confirm how long alarm equipment is expected to remain operational, whether signals have a secondary communication path, which cameras will continue recording, and whether monitoring contacts and response procedures are current.
Those are practical questions that are easier to answer while the lights are still on.
ABC Fire & Burglar Alarm works with retail stores, restaurants, hotels, offices, warehouses, and other commercial properties across New Orleans, Metairie, Kenner, Slidell, Covington, Gretna, Chalmette, Hammond, and surrounding communities.
